boards: shields: lcd_par_s035: configure TE signal for RW612

Configure the TE signal for the rw_rw612_bga board when using the
lcd_par_s035 shield. This signal should be handled on the rising edge in
the default configuration, since the display writes from the MCU are
faster than the panel reads data.
